Knak allows you to place a background image behind other bits of content such as text and buttons. That way you can edit the content in front of the image.
Traditionally some marketers have refrained from using background images due to lack of support in some email clients. With Knak's updated email editor you can rest assured your background images will work everywhere!
Take a look at the screenshot below, this section is using a row background image with a text box and button over the top.
To set this up, select the row in which you want to add the background image. On the right you will see the Section Attributes. Select an image to use from your Knak image library or paste in an external URL.
Knak gives you several options for how the background will can be displayed:
The background image is displayed in its original size unless it exceeds the size of it’s container when it will be 100% width
Resizes the background image to cover the entire container, even if it has to stretch the image or cut off some of the image
Resizes the background image to make sure the image it's fully visible. This setting will shrink the image height if the height of the container is smaller than the image
Stretches the image across the whole content box. Not recommend unless you're trying to create a stretched affect
Image will be repeated until it fills the row dimensions. Good for creating a pattern using a small, repeatable image.
The image will span the full width of the email, not just the content area.
We recommend playing around with the settings to ensure your image displays as desired.
